Definitions

  • the invention relates to a current-carrying profile connector with plug contacts and a Isolierstoffgeratiuse, the receiving chambers for receiving a plug contact, conductor insertion openings on a first end side of the insulating material, which open into a respective receiving chamber, and insertion openings on a second end face of the insulating material, the first end face diametrically opposite and providing access to a respective receiving chamber has.
  • the invention further relates to a current-carrying arrangement with a plurality of current-carrying profiles, which have a carrier profile with a base surface, mutually parallel webs on the base surface and respectively by a pair of webs limited grooves and electrical conductors in such grooves, and with the above Strom Equipmentsprofil- connectors.
  • busbar systems For distribution of electrical energy in a building and for connecting lights at selectively selected positions busbar systems are known with current-carrying profiles, which have a comb-like cross-section with ridges and grooves formed therethrough and received in the grooves electrical conductors.
  • these electrical conductors are received in the grooves, for example on the side walls of the webs and can be electrically conductively contacted by a tap connector with protruding into the grooves contacts.
  • the current-carrying profiles usually have a carrier profile formed of plastic material, which is installed in a metal trough. They have a relatively large extension length. In the usual thermal stress, the electrical conductors formed of metal, the metal trough and the carrier profile formed of plastic expand differently.
  • EP 1 284 033 B1 shows a current-carrying profile with a wire support member with grooves, in which electrical wires are accommodated.
  • the wire support members have at their ends projections, which overlap with two merged wire support members overlapping.
  • the projections thereby form a composite channel for the wire in the transition region of two wire-holding elements and allow, for example, temperature-dependent length compensation of the wire-holding elements to one another.
  • the plug-in contacts are displaceable in a direction from the first end side to the second end face of the insulating material extending plug-in direction are received in a respective receiving chamber.
  • the plug contacts have on the side facing a conductor insertion opening a spring connection contact with a clamping spring for clamping an electrical conductor and on the side facing a plug opening formed from at least one pair of spring arm with two opposing spring arms fork contact or formed from a protruding in the insertion direction contact blade blade contact.
  • the plug contacts have between the clamping spring of the spring connection contact and the fork or blade contact a stop for abutment of an electrical connector clamped to the spring connection contact, wherein the clamping spring is inclined towards the stop and in relation to the plugging direction.
  • the electrical connection of electrical conductors of fluently arranged in a row current management profiles is done with such current guide profile connectors.
  • the electrical conductors of the current-carrying profiles can then be inserted in each case in a conductor insertion opening and clamped to the local spring connection contacts.
  • Two such current-carrying profile connectors can be plugged together at their plug-in openings, wherein a blade contact of a first current-carrying profile connector cooperates with a fork contact of a second current-carrying profile connector.
  • a current-carrying profile connector does not necessarily have to have the same type of plug contacts as either blade contacts or only fork contacts.
  • plug-in contacts may be present in mixed form, such as e.g. Knife contacts and fork contacts.
  • the plug contacts are arranged displaceably on a respective receiving chamber of the insulating material, they can move in their insertion direction at a different longitudinal extent of the clamped electrical conductor and the carrier profile.
  • the blade contact can move relative to the fork contact in such a movement, without the electrically conductive Connection between the blade and fork contact is impaired.
  • the relative movement of a connector with a longitudinal extension of the clamped electrical conductor to the stationary insulating material while ensuring a stationary clamped electrical conductor spring clamp contact is achieved in that the electrical conductor abuts the stopper of the plug contact with its front side and fixed in position by the clamping spring on the Plug contact is clamped. This is achieved in that the clamping spring facing towards the stop and is inclined with respect to the plugging direction.
  • the clamped to a plug-in electrical conductor of the current-carrying profile is prevented to one side by the stop and to the other side by the clamping spring to move relative to the plug contact. Nevertheless, a sliding movement remains possible by the pairing of a fork contact with a blade contact of the interlocking current-carrying profile connectors, in order to ensure the length compensation in this way.
  • the blade contact and / or the fork contact at least on the contact surfaces have a surface coating, which ensures an even better sliding movement with constant contact resistance.
  • a surface coating may be provided by a noble metal overlay, such as e.g. be realized by gilding, by silver coating or the like.
  • the plug contacts may be integrally formed from a sheet metal part and have a bottom surface and from the opposite sides of the bottom surface projecting side walls. A conductor guide tunnel is provided by these side walls spaced apart and projecting in the same direction from the bottom surface.
  • the plug contact has at least one clamping spring, which is each released from a side wall.
  • the side wall in the region of the clamping spring can be cut free from the base plate or punched free and the side wall can be separated transversely to the plane of the bottom surface.
  • Such integrally formed with the side wall and connected thereto clamping spring can then bent out of the plane of the side wall in the direction of the opposite side wall his. It is also conceivable that a separate clamping spring is connected to a side wall, for example by soldering, welding, caulking or other joining.
  • Such a plug contact is very simple, built by the projecting side walls stable and compact.
  • a material flap may protrude to form a stop.
  • This material flap can be arranged in a space between the opposite side walls.
  • the tunnel for insertion of an electrical conductor is bounded laterally by the two side walls, from below through the bottom plate and in the insertion direction by the material lables.
  • An electrical conductor of the current-carrying profile introduced into the conductor guide tunnel between the side walls can then be led up to the material lug in order to lie there.
  • the electrical conductor is clamped by the protruding from the side wall clamping spring on the plug contact and not only electrically contacted, but also fixed in position held on the plug contact.
  • the side walls may be oriented at an angle to each other at the transition to the fork or blade contact. In this way, the connector is further tapered in the insertion direction of the spring connection contact.
  • This area formed by the mutually facing obliquely set side walls is preferably in the region in which the stopper is formed.
  • the obliquely aligned side wall portions may form the spring arms of a fork contact in a separate section from the bottom plate.
  • the spring arms of the fork contact close to the side walls of the plug contact and are kept stable by the one-piece connection.
  • a sufficiently large current cross section is ensured in this way.
  • the pair of spring arms may then have a contact area at the spring arm ends remote from the spring connection contact, followed by insertion portions bent away from each other.
  • an insertion funnel for inserting a blade contact is provided in the fork contact and realized at the oblique insertion sections subsequent contact area with low contact surface.
  • the contact pressure of the fork contacts is concentrated on this contact area with a reduced area and in this way increases the surface pressure and reduces the contact resistance.
  • the obliquely aligned side wall portions may merge into adjacent contact lugs which extend parallel to each other and form a blade contact. This also achieves direct current transmission via the side wall sections into the blade contact with the greatest possible current cross section and stable construction.
  • the risk of bending the blade contacts is reduced.
  • the increased blade thickness is also advantageous in terms of achievable contact forces on the fork contacts, as they thus require no bias.
  • a ground contact can be slidably plugged into the plug contact and protrude from the plug contact.
  • This embodiment is in principle independent of the specific embodiment of current-carrying profile connectors.
  • grounding contact fixed in position can remain connected to grounding potential, for example, the metal trough, even if the carrier profile or built-in electrical conductors move. Due to the displaceable plug contact of the earthing contact on a plug contact, which is used to connect two current-carrying profiles, a movement of the connector on the fixing of the ground contact does not affect, since they are slidably plugged together.
  • the ground contact may have a socket contact into which the contact tab of a connector described above is plugged.
  • This contact lug of the connector can also be connected to a forked contact of a complementary connector to provide in this way a continuous wiring and at the same time a ground connection to protective earth (Protective Earth-PE).
  • a current-carrying profile connector is connected to the end face of two carrier profiles arranged one behind the other in alignment.
  • the protruding from the front electrical conductor of the carrier profile are clamped to a respective spring terminal contact of a plug contact of the current-carrying profile connector.
  • the electrical conductor abuts against the stop of the plug contact and is clamped with the clamping spring on the plug contact.
  • the connected at the adjacent end faces of the two carrier profiles current guide profile connector interlock.
  • a blade contact of a plug contact of a current guide profile connector is slidably contacted with a fork contact of a plug contact of the other current lead profile connector.
  • two carrier profiles arranged in alignment one behind the other are connected by a pair of complementary current-carrying profile connectors, which are respectively connected adjacent to each other on one end face of the two carrier profiles.
  • the projecting from the carrier profiles electrical conductors are inserted into the conductor insertion openings of the current-carrying profile connector to be clamped with a spring connection contact.
  • the plug contacts of the complementary current-carrying profile connectors can move relative to one another, whereby a sliding, linearly displaceable plug-in direction in the plug-in direction of the two complementary current-carrying profile connector and thus of the support profiles arranged in a row is ensured by the blade and fork contact arrangement ,
  • a first current-carrying profile connector can be plugged.
  • This first current-carrying profile connector is then plugged together with a second complementary current-carrying profile connector in that they mesh in the region of their plug-in openings.
  • a blade contact of a plug-in contact of one of these current-carrying profile connectors dips into a fork contact of a plug-in contact of the other current-carrying profile connector. In this way, a sliding, displaceable in the insertion direction contacting the two interconnected plug contacts is ensured.
  • the insulating housing of the current-carrying profile connector can have an outer contour adapted to the end contour of the end faces of the carrier rail and can be inserted flush into the end-face contour.
  • the current-carrying profile connector is fixed in position to the region of the end face of the carrier profile and prevents relative movement of the current-carrying profile connector relative to the carrier profile or at least severely limited.
  • the front side contour of the carrier profile and the outer contour of the current-carrying profile connector can have latching elements for locking the current-carrying profile connector to the carrier profile. In this way, it continues to succeed, the current-carrying profile connector after attaching to the front side of the carrier profile on the Lock the carrier profile and secure it from being pulled out. This locking can be so strong that the current-carrying profile connector fits snugly against the carrier profile and is held firmly by form-locking on the carrier profile.

  • the carrier profile 8 has a number of mutually parallel webs 10, each defining a groove 11 for receiving a respective electrical conductor 9. It is clear that alternating grooves are provided with different depths, so that the electrical conductors 9 are arranged on two height levels. The electrical conductors 9 protrude at the end faces of the carrier profile 8 out of this, in order to be contacted in an electrically conductive manner.
  • the carrier profile 8 has a platform 12 for supporting a current-carrying profile connector 1a, 1b.

Also on this front page can be a power guide profile connector 1a are plugged with its the conductor insertion openings 4 having end face 3 and rest on the platform 12.
  • the contour of the current-carrying profile connectors 1a, 1b in the region of the conductor insertion openings 4 and the first end face 3 is adapted to the current-carrying profile 8 such that the current-carrying profile connectors 1a, 1b are slid suitably onto the platform 12 with their side walls can be positioned in this way in the correct position to the electrical conductors 9 and the associated conductor insertion openings 4.
  • the platform 12 has lateral, vertically projecting side walls, wherein the side walls in the plugged state of the current-carrying profile connector 1a, 1b engage in recesses on the respective current-carrying profile connector 1a, 1b.

  • This second type of plug contacts 17b also have a conductor terminal contact 18 for clamping the electrical conductor 9 of a current-carrying profile 7 and at the other end a fork contact 20.
  • This is also formed by two obliquely placed spring arms which receive a blade contact 19 between them and by spring force Connect. It is clear that the blade contact 19 is slidable relative to the fork contact 20 in the insertion direction S, so that the insertion depth of the blade contact 19 in the fork contact 20 can vary.

It is even more clearly seen that the nested pairs of first and second plug-in contact 17a, 17b in the insertion direction S are relatively displaceable to each other, so that between the respective blade contact 19 and the associated, formed by the spring arms 26 fork contacts 20 a Gleitcard ist is made.
  • the blade contacts 19 and / or fork contacts 20 may be surface-coated in order to improve the current transfer between the blade contact 19 and the fork contact 20 which is connected thereto. This can change the insertion depth of the blade contacts 19 in an associated fork contact 20 to compensate for changes in length of the interconnected electrical conductors 9 and to compensate for length tolerances.
  • FIG. 9 shows a sectional view of the current-carrying arrangement with only a pair of first and second plug-in contacts 17a, 17b inserted into the receiving chambers 16 of the main body 14 of a first and second insulating housing 2a, 2b.

  • This receiving slot 29 is the conductor insertion opening 4 for the same receiving chamber 16 diametrically opposite.
  • This receiving slot 29 is adapted to the blade contact 19 so that it is displaceable in the receiving slot 29, but can not be tilted in a different direction than in the insertion direction.
  • the receiving slot 29 forms part of the insertion opening 6, which provides access to the blade and fork contacts 18, 19 for insertion of a complementary current-carrying profile connector 1a, 1b allowed and opens into the associated receiving chambers 16.
  • the receiving chamber 16 in the main body 14 of the second insulating 2b also has two spaced apart from each other with a web 30 guide slots 31 which are adapted to receive a respective spring arm 26 of a fork contact 20.
  • FIG. 10 shows the sectional view of the current-carrying arrangement FIG. 9 with the difference that the position of the plug contacts 17a, 17b in the respective receiving space 16 is changed by lengthwise extension of the electrical conductors 9. It is clear that the fork contact 20 abuts with its insertion portions 28 to the boundary walls of the guide slots 29 of the complementary current-carrying profile connector 1a. This is an end position for the second plug contact 17b, which, as in FIG. 9 shown at the other end position gap-free against the lid part 15.
  • the first plug-in contact 17a is in the illustration of FIG. 10 in a position in which it rests with its leading to the conductor connection contact 18 gap without a gap on the cover part 15.

The locking lugs 32 dive into latching openings 33 of the base body 14.
  • the conductor insertion openings 4 in the cover part 15 are arranged on two planes and alternately offset therefrom.
  • first and second plug contacts 17a, 17b are arranged in alignment with the diametrically opposite conductor insertion openings 4 of the two current-carrying profile connectors 1a, 1b. In this way, in the case of a very flat construction, the electrical conductors 9 of two current-guidance profiles 7 arranged adjacent to one another in alignment can be connected to one another.
  • FIG. 12 shows the side sectional view of the current-carrying profile connectors 1a, 1b.
  • FIG. 11 It is clear that the current-carrying profile connectors 1a, 1b are each supported on a platform 12 of a current-carrying profile 7, wherein the front side of a current-carrying profile 7 outstanding electrical conductor 9 through a conductor receiving opening 4 in the first end face 3 in a associated receiving chamber 16 are guided. It can be seen that the electrical conductors 9 abut with their free end against the stop 21 of the plug-in contact 17a, 17b arranged in the receiving chamber 16.

It is also clear that the blade contact 19 are encompassed on both sides by the spring arms 26 of the fork contact 18.
  • FIG. 14 shows a perspective view of the nested pair of current-carrying profile connectors 1a, 1b without the main body 14. It is clear that the plug contacts 17a, 17b partially directly against the adjacent cover part 15 or spaced therefrom with a gap. This depends on the respective longitudinal extent of the electrical conductor 9 clamped thereto.
  • the conductor insertion openings 4 are arranged in the cover parts 15 on each in a row on two height levels. Between two conductor insertion openings 4 of a row is alternately offset another conductor insertion opening 4 arranged in a height offset thereto arranged plane, which form a second row.
  • FIG. 15 shows a side sectional view through the Strom.sanix. It is clear that the conductor insertion openings 4 are located on several, here for example two height levels and the plug contacts 17a, 17b alternately offset are also arranged on these two height levels.
  • FIG. 16 shows a partial perspective sectional view of a current-carrying arrangement in which a current-carrying profile 7 is installed in a metal trough 34.

  • the current path can be divided into two electrical conductors 9 of a common current-carrying profile 8 to be clamped.
  • the power line cross section can be increased.
  • FIG. 18 shows the pair of first and second connectors 17a, 17b FIG. 17 in the perspective view with a view of the conductor connection contacts 18. These are again for clamping each of an electrical conductor designed as a spring terminal contact and have for this purpose at least one Federarmcru, which is formed of two opposing spring arms 22.
